What is DNS explain its working with Example?
The Domain Name System (DNS) is a network of directories on the internet used to resolve host names (e.g., www.gingernameclub.com) into machine-readable IP addresses (e.g., 192.168. 106.81). Every computer, node, device or resource on the internet has a unique name and unique IP address.
What is DNS and its types?

How do you explain DNS?
DNS is the protocol that provides the framework for web browsing. In other words, DNS is a system of computers that provides the infrastructure that allows us to browse the Internet by making the Internet a more human-friendly place. Computers address each other with numbers called IP addresses.
What layer is DNS?
In OSI stack terms, DNS runs in parallel to HTTP in the Application Layer (layer 7). DNS is in effect an application that is invoked to help out the HTTP application, and therefore does not sit “below” HTTP in the OSI stack. DNS itself also makes use of UDP and more rarely TCP, both of which in turn use IP.
What is DNS and its purpose?
Domain Name Servers (DNS) are the Internet’s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.
